median vs IQR skewed data uses these for center and spread Histogram - when to use Based on the shape of the distribution, uses mean + standard deviation OR median + IQR to describe center and spread - Larger data sets; shows shapes of distribution and potential outliers; ignores the individual data valuesl Histogram Skewed right Not a symmetric distribution, the tail is on the right Standard Deviation Rule 68% of the data are within 1 standard deviation, 95% are...

Descriptive statistics Inferential statistics __ are used to synthesize and describe data. It allows us to draw conclusions from the use of graphs, charts, and so on. __are used to make inferences about the population based on sample data. It allows us to say whether difference is significant. They infer or draw a conclusion, based on laws of probability. Mode Median--doesnt take into consideration outliers Mean Differential: The __ is the number that occurs most fq in distribution. In the fo...
